swap color with texture

I have a question regarding colors and textures. I would like to use a texture for several parts of my animation, including the lines of my vectorized scans.
Is there some way or workaround to swap a certain color with a texture? It is quite tedious to do it manually for every single frame.

There is no way to do this automatically. You must use the paint bucket or the select tool.

To do use the select tool to do this, you can select the lines in the camera or drawing view, then click on the color to assign it.

Also, “select all strokes with selected color” may help a lot doing so. You just choose from your palette the color you want to swap, go to the camera/drawing view, press the shortcut or look for the option in the drawing menu, and swap it manually… That should help a little.
